Design and Implementation of Digital FIR Filters

摘要: Publisher Summary Finite impulse response (FIR) digital filters possess several properties that make them attractive for a wide range of applications. An exactly linear phase-response can be achieved with FIR filters, the result they used in reconstruction signals without phase distortion. Under most practical situations, high orders implemented efficiently by indirect design approaches. One major advantages is near-optimal multidimensional designed easily starting from one-dimensional (1-D) prototypes and using spectral transformations. naturally lend themselves to efficient implementation multirate signal processing algorithms achieve extremely sampling rate conversions. Many techniques have been advanced filters. This chapter presents including recent procedures lead implementations. It reviews filter preliminaries discusses windowing technique design, particular emphasis on Kaiser's window, optimal designs equiripple weighted error, emphasizing Remez exchange developed McClellan Parks. The also maximally flat programming designs.
